🏷️ Basic Information

Make:

BMW

Model:

5 Series

Model Variant:

525i

Year:

1995

Chassis Code:

E39 (for North American market, specifically the 525i variant which was not originally part of the E39 launch but might be associated with later models or specific market configurations. However, 1995 is typically associated with the E34 generation in most markets. For the purpose of this manual's context and likely target audience, it's important to clarify that the E39 generation began in late 1995 for the 1996 model year in Europe. The 1995 model year in North America would primarily be E34. Given the manual explicitly states 525i 1995, it's most likely referring to a specific variant or a typo in the model year association, or potentially covering early production of E39 that was designated as 1995 production for the 1996 model year. Assuming the manual is correctly referencing the target vehicle, it points towards an early E39 or a late E34 model with the 525i designation.)

Engine Code Common:

M50B25 (common for 525i of this era, though E39 might have introduced the M52 variant)
